Mr. Do! M.A.M.E Arcade Session
0Mr. Do! is a 1982 maze game developed by Universal. It is the first arcade video game to be released as a conversion kit for other arcade machines; Taito published the conversion kit in Japan. The game was inspired by Namco's Dig Dug released earlier in 1982. Mr. Do! was a commercial success in Japan and North America, selling 30,000 arcade units in the US, and it was followed by several arcade sequels.
The object of Mr. Do! is to score as many points as possible by digging tunnels through the ground and collecting cherries. The title character, Mr. Do (a circus clown—except for the original Japanese version of the game, in which he is a snowman), is constantly chased by red monsters called creeps, and the player loses a life if Mr. Do is caught by one. The game ends when the last life is lost.
Mr. Do collecting cherries while avoiding Creeps.
Cherries are distributed throughout the level in groups of eight. A level is complete either when all cherries are removed, all creeps are destroyed, "EXTRA" is spelled, or a diamond is found.
Mr. Do can defeat creeps by hitting them with his bouncing "power ball" or by dropping large apples on them. While the power ball is bouncing toward a creep, Mr. Do is defenseless. If the ball bounces into an area where there are no creeps to hit (such as behind a fallen apple), Mr. Do cannot use it again until he has retrieved it. When the power ball hits a creep, it then reforms in Mr. Do's hands after a delay that increases with each use.
Mr. Do or the creeps can push an apple off the edge of a vertical tunnel and crush one or more creeps. If an apple falls more than its own height, it breaks and disappears. Mr. Do can also be crushed by a falling apple, causing a loss of life.
Occasionally, the creeps transform briefly into more powerful multicolored monsters that can tunnel through the ground. If one of these digs through a cherry, it leaves fewer cherries for Mr. Do to collect. When it digs under an apple, it often crushes itself, other creeps, and/or Mr. Do.
Every time the player's score passes an even multiple of 5,000 points during play, a letter from the word "EXTRA" appears on the playfield as an Alphamonster, and the player can defeat or be defeated by this monster in the same way as a creep. Defeating an Alphamonster awards that letter to the player, and collecting all five letters of the word completes the level, plays a cut scene playing the theme to Astro Boy, and awards the player an extra life. Alphamonsters attempt to eat any apples they encounter, which makes them difficult to crush.
The creeps spawn at the center of the screen. After they have all appeared, the generator will turn into a food item; picking this up scores bonus points, freezes all the creeps, and calls out an Alphamonster and three large blue monsters. The latter can eat apples as well. The creeps stay frozen until the player either defeats all three blue monsters, defeats the Alphamonster (in which case any remaining blue monsters are turned into apples), loses a life, or completes the stage.
Rarely, dropping an apple reveals a diamond which, if collected, completes the level and awards a bonus credit to the player.
